Polymer materials have many fields of application, such as in agriculture and agribusiness, medicine, consumer science, the automotive industry, for sports equipment etc. These materials are generally produced by injection molding, in-mold shaping and extrusion. A machining process is essential however both for small quantity production for complex and accurate shapes. Moreover, it is known that the demand for machining, especially with respect to the drilling of polymer materials has increased. In this study, the cutting temperature for drilling pure polyamide and carbon black reinforced polyamide was investigated as well as the effects of drill point angle, cutting speed, and feed rate on cutting temperature making use of Taguchi and ANOVA statistical methods. Among the selected drilling parameters, the most significant was found to be the drill point angle and the least effective the feed rate.
